Simple Synthesis of Visual Textures and Perceptual Asymmetry
ثبت نشده
چکیده
A scheme is proposed to synthesize visual textures with positional jitter and/or orientation randomness that are widely used in controlled psychophysical experiments for modelling (human) preattentive vision. The scheme, though simple, has been found to be quite effective for that purpose. Spectral properties of synthesized textures are then analyzed with the goal of creating a framework for computing signal-tonoise ratio from the spectra that offers the potential to interpret quantitatively certain perceptual phenomena, such as perceptual asymmetry.

Contrast Negation and Texture Synthesis Differentially Disrupt Natural Texture Appearance
Natural textures have characteristic image statistics that make them discriminable from unnatural textures. For example, both contrast negation and texture synthesis alter the appearance of natural textures even though each manipulation preserves some features while disrupting others. Here, we examined the extent to which contrast negation and texture synthesis each introduce or remove critical...

Objectives: Paper and pencil exercises are extensively used to enhance children’s visual perceptual skills, while exercises involving volumetric shapes have been neglected. The present study aimed to develop a combined training package, including volumetric shapes and paper and pencil exercises, and to investigate its effectiveness in strengthening the visual perceptual skills of preschool chil...
متن کاملTHE EFFECT OF POSTERIOR CEREBRAL PULMONARY DIRECT ELECTRICAL STIMULATION (TDCS) ON IMPROVING SPATIAL, VISUAL, AND VERBAL PERCEPTUAL ABILITIES
Background & Aims: Direct electrical stimulation of the brain is a therapeutic technique that can be effective in improving visual, verbal, and spatial perception. The present study investigated the effect of direct electrical stimulation (tDCS) of the posterior parietal cortex on improving spatial, visual, and verbal perceptual abilities. Materials & Methods: In this quasi-experimental study,...

متن کاملCurvature-based perceptual singularities and texture saliency with early vision mechanisms.
Recent work has shown that salient perceptual singularities occur in visual textures even in the absence of feature gradients. In smoothly varying orientation-defined textures, these striking non-smooth percepts can be predicted from two texture curvatures, one tangential and one normal [Proc. Natl. Acad. Sci. USA103, 15704 (2006)]. We address the issue of detecting these perceptual singulariti...
